Merge branch 'udp-fix-two-integer-overflows-when-sk-sk_rcvbuf-is-close-to-int_max'
Kuniyuki Iwashima says:
====================
udp: Fix two integer overflows when sk->sk_rcvbuf is close to INT_MAX.
I got a report that UDP mem usage in /proc/net/sockstat did not
drop even after an application was terminated.
The issue could happen if sk->sk_rmem_alloc wraps around due
to a large sk->sk_rcvbuf, which was INT_MAX in our case.
The patch 2 fixes the issue, and the patch 1 fixes yet another
overflow I found while investigating the issue.
